SIGNALING DEVICE y Filed March 3l, 1930 however, that the casing and end disks12 patented Vug. 2,5, 1931 UNrrrzn STATES'y SAMUEL M. DOVER, 'or CHICAGO, ILLINOIS j SIGNALING DEVICE Application' My invention relates more particularly to signaling devices employingA compressed air as the operating medium and more especially to signaling devices for use on vehicles.

My object is toprovide a novel, simple, durable, and relatively inexpensive construe tion of signaling device of the character above stated and preferably of such construction as adapts it to be hand operated.

Referring to the accompanying drawings:

Figure 1 is a broken view in longitudinal sectional elevation of the forward end of an automobile showing it as equipped with a signaling device embodying my invention..

Figure 2 is a view in side elevation ofthe signaling device.

Figure 3 is an end view of the device.

Figure 4 is a broken plan view of the device. f

Figure 5 is a broken section takenat the line 5-5 on Fig. 2 and viewed in the direction of the arrows. v

Fig. 6 is a section taken at the lines 6-6 on Figs. 8 and 7 and viewed in the direction of the respective arrows; and 4 Figure 7, a broken section .taken at the line 7-7 on Fig. 2 and viewed in the direction of the arrows. i i 4 The signaling device shown comprises a casing 8 at which the device would be supported in any desirable position for use, in the arrangement shown, where it is illustrated as provided on an automobile, the casing 8 means of a bracket 10. It will be understood, 8 may be located, if desired, at any other suitablev place and secured in position in any desirable way.`

The casing 8 is formed of a central cylindrical member 11'open at its opposite'ends containing recesses 13 into i which the ends of the member 11 extend, these parts being held together by screws 14 located p at the margins of thedisks. y

The disks 12, which are of the same form and size, are each provided at its circumference with a hollow projection 15 which eX- tends crosswise of thedisk, one end of each `projection 15being of a width considerably greater thanone-half the thickness of the the openings vin ywhich'it is secured.

casing, as represented at 15, `and the other end being vof a width considerably less than .one-half of thewidth of the casing, as represented' at kr17 the projection 15, inthe assembling of the disks 12 with the vmember 11, 55 bein-g so disposedV as to interiit with'each other `as shown more particularly in Fig. 3 in which position the larger portions 16 of theprojections 15 'are disposed in staggered relation. v Thedevice also comprises compressed-air 60 operated sound-producing devices, which may be of any desirable type. Twol such sound-producing devices, shown as constructed to produce different tones, are employed in the construction shown., these devices being represented at 18 and being screwed into 19 in the portions 16 of the projections 15. The sound-producing devices 18 are open at the ends thereof` at which they are screwed into the openings 19 and thus 70 each opens into the one ofthe projections 15 for operating the de f The compressed air in the ,casing 8 of the vices 18 is generated device bya'double-acting piston reciprocable 75 in the member 11 as .hereinafter described, the projection-equipped disks 12 containing openings therethrough forcausing the interior of the-member 11 to communicate at its .oppositel ends with the spaces in the projec va0 tions 15respectively, and with whichthe sound-producing devices 18 communicate. The opening above referred to and at one end being secured to the top of the engine 9 by of the member 11, for one of the devices 1.8 is represented at 20, its outer end being closed .by a plug 21. The opening at 22 and is formed with a pair of cup leath- 95 yers 23 disposed back to back l and connected with a piston rod 24 whichis slidable lin an 25 in the center of one of the disks 12, a coil spring 26y surrounding the rod 24 and confined between vthe piston properand 10Q the opposite one of the disks 12 being provided to return the piston to the position shown in Fig. 5 following the actuation of the piston out of said position.

It will be understood from the foregoing description that when the piston 22 is moved to the left in Fig. 1, the air in front thereof will be compressed and forced out through one of the devices 18,' thereby producing a tone and that when the piston is moved in the opposite direction it will operate to force air through the other device 18 and thus cause a tone to be produced thereby, the spring 26, as above stated, operatinor automatically to shift the piston in the tlast-referred-to direction.

In the arrangement shown the piston 22 is operated by hand from the dashboard of the automobile and represented at 27, the dashboard being shown as equipped with a rod 28 slidable therein provided at one end with a hand grip 29 by which it may be drawn on in a direction away from the casing 8 and a Wire connection 30 between the rod 28 and `the piston rod 24, the casing 8 being so arranged that pull on the rod 28 acts in the same general direction as that in which the rod 24 extends, whereby the piston 22 may be operated to force actuating air pressure to the device 18, alternately, merely by the 0perator pulling the rod 28 to shift it to the 'left in Fig. 1 and thereupon releasing his grasp upon the rod to permit'the sprinor 26 to act.

While I have illustrated and described a particular construction embodying my invention, I do not wish to be understood as intending to limit it thereto as the same may be variously modified and altered without de arting from the spirit of my invention.
